I would suggest that they are to add separation between the plasma conduits and a manway to the nacelles. Adding the vacuum of space between people and heat, radiation and potential hazards is a way cheaper and easier method of protection than say heavy armor or building specialized energy shields for the task.
It could also add separation between the coolant and the warp plasma. If the warp plasma heated the coolant, both would be less effective. One section of the pylon channels plasma, and another channels coolant.
Exactly what I was thinking as well. And they could run control systems up one side and plasma through the other - physical separation means that, if the conduit blows out/leaks/fails (somewhat) catastrophically, you might still be able to do a manual shutdown or otherwise triage the situation. EDIT: Plus, a vacuum gap is less likely to fail than energy shielding, and would presumably add less mass than radiation shielding plates or the like.
I was going to suggest this exact thing. Of course there is probably a jefferies tube running along side the conduit for maintenance, it is likely highly irradiated, but by have a separate tube as well it allows access to the nacelles without the need of a radiation suit along with a conduit for such things as the a fore mentioned coolant, wiring, GNDN pipes, and other support systems that probably wouldn't function as well when competing with the plasma conduits for heat expulsion.
I was just about to write your theory. Much cheaper than building an extra think wall to separate people from incredible energy levels. Remember when Scotty had to crawl thru an energized Jeffery-tube.

As an architect, my first thought was it's because of heat just like Henry mentioned. I mean for someone with the slightest idea of how stress work it should be pretty obvious. Even for an architect ;)

I'm perfectly fine with assuming that it's for aesthetics even in-universe. You can't tell me Starfleet doesn't care about how their ships look, otherwise they wouldn't look so damn good.
I'm quite partial to the design of the borg cube.. Seems everything I ever design in Minecraft, 'Space engineers' or 'The Raft', they all tend to be flat squares.
100%. Not as badly as once structural support fields are introduced, which seem reliable enough that eventually the universe class throws structural sanity out the airlock entirely, but aesthetics seem to have always been a big consideration for starfleet designers. Which is a-okay, it obviously works well enough for them.
If your main method of expansion/economic growth/whatever else is diplomacy, you want good looking ships. Sleek ships make you look rich and technologically advanced. Intimidating ships make you look powerful. Fast looking ships means criminals might not be as inclined to try to run from you. And so on.

The issue with your surface area statement is that most of the surface area inside the cutout is radiating /towards/ the face of another ship component, allegedly also a radiating/cooling surface. This means that that surface area isn't actually eliminating heat, because that heat is going back into your ship. It could just be a separation of the in-flowing warp plasma and the plasma flowing back to the warp core. Ship designers saw the two magnetic "pipes," and thought "you know what, we could just cut out that section of the hull right there, and it wouldn't do anything. Why not?"
On the topic of heat radiation, I have always assumed that the warp grilles are actually heat radiators operating at very high (10000 Kelvin +, judging by their bluish glow) temperatures, to maximize radiance as per the Stephan-Boltzman Law: 𝑷 = 𝐴𝜀𝜎𝑇⁴ Where *A* is area, ε is emissivity of the radiator material, σ is the Stephan-Boltzman constant, and 𝑇 is the radiator temperature. As you can see, the temperature is to the power of four, meaning that doubling the radiator's operational temperature increases the amount of power it can radiate away sixteen-fold. There are a few caveats to this idea however that I won't go into too much detail here unless anyone wants to know, but I find it a fun way to rationalise an iconic element of Trek ship design and solve the heat dissipation issue of these supposedly radiator-less ships.
The little fins on the TOS model were supposed to be radiators.... I think they underestimated the scale a tad. Other possible invisible to us solutions could be high intensity lasers on a non visible part of the spectrum. Ejecting heated particles from the hull to effectively create as large a radiator as you might need, this can be a total loss system as used on some real space craft or using the known tech of trek the particles can be reclaimed by some version of the various fields used by the ship already. Dump your waste heat in subspace or something, invariably pissing off some native alien species for a single episode. Built in environmental message right there.
Sorry to bust your bubble, but that blue glow within the warp nacelles is the electromagnetic plasma interacting with the warp coils, thus generating the warp field. EM plasma-in and of itself-is invisible in a vacuum: no atmospheric gases for it to fluoresce.

@OriginalTharios yeah I know, right? The whining about Discovery and childish "STD" name calling is hilariously silly. Like, why did early versions of the original Enterprise have those spikes on the nacelle tips? Because they looked cool.
There certainly is an out-of-universe reason. They need to deliberately make their derivative version instantly recognizable (because the original version is so iconic) ... and they need to deliberately make it look unique (because they wanna sell toys and collectibles and merch - and licenses to the same - without paying revenues towards original designers). In-universe reasoning is deliberatelu unexplained. Because fans always work out explanations and apologetics to validate inconsistencies in canon. Maybe the cutout holes are because they ran oit of shipbuilding metals, lol.
@@pwnmeisterage I'm not sure if making it recognisable and making it unique are actually two different things, your comment may contain unnecessary redundancy. Edit: I later agreed this comment was incorrect, as per P's response.
They stole the design from the movie Enterprise , 1979-1991. So since they stole that design , they had to make it look slightly different, thus that cut out. Clever huh?.

Great video as usual! The cutouts alone would not increase the rigidity unless the edges are extended past the original surface. The airplane cutouts are a perfect example but notice how the sheet metal is bent out effectively multiplying it's thickness which increases rigidity.

That was my thought too. Then I thought, what if there were smaller angled structures in there to radiate the heat away at a 45° angle? They should do that with the whole surface of the pylon. With triangular prisms, you could increase the total surface area by a factor of 1.4... And since it doesn't matter how small the triangular structures are that's probably what they'd be doing. And with this, the cutout makes sense again for cooling.
And why you even think that enclosed area inside pylon is equal to cutout and radiating energy out even if some of it just act on another side of cutout? Nullified is wrong word there and clearly you are wrong.
yup my thoughts exactly, the design doesn't make sense period. If heat radiation were the goal why isnt the entire surface full of radiators which are as close to blackbody radiators as possible ? a folded design, maybe even incorporating mirrors and lenses might be a realistic move ...
Very clever! See, this is why I can't get accept the idea of a 'visual reboot, but it's still the same ship.' Like... the pylons have a hole, or they don't have a hole. Having a hole isn't just another 'look' for not having a hole. They're two very different things. So, I really can't accept them as being the same ship; it's a ship with holes in its pylons, or it isn't; it's not both. :-) But... if the holes are there, this is a very plausible explanation for why. Bravo.
I would love to see a rerender of the Battle of Endor from you using all your designs! I think it's a pitty, that this amazing space battle is visually very outdated. Most ships are just so blury and often have weird blueish looks. Even just seeing a couple of shots from the movie being reimagined by you would be amazing!!!
For your second point, I was under the impression futuristic shaped EM fields are use to prevent drive plasma from touching the walls of the conduit(s) and melting them. So the idea of keeping the conduits cool doesn't make a lot of sense because the plasma is not in direct contact with the conduit itself to transfer that heat.
Also an electromagnetic system has much less resistance when cold. If they use a highly efficient superconducting magnet system, they would have to be keeping it very cold.
The cut could also change the vibration modes of the nacelles. Goes with the stresses you mentioned. One could also twist the physics of warp drive to allow for some gain in speed or efficiency from warp field dynamic but that's way more thinking than most people want to do. Perhaps more time on the stories.
1. Allows the pylons and Na-cells to be flexible in turbulence. 2. The area has these Star Trek "thingy units" that produce Star Trek "thingies" in the space. Space smoke, space lighting, radar disruption features, sensor features. 3. Area collects required gas materials in Nebulous flight or high orbit gas planet flight to later be processed for long space duration flight - like Nobel gases required for life. (like in Lost in Space season 2 when they collect the gases to clean the water system) 4. That particular version of pylon and na-cells do not have a flight or engineer system that would be in that usually housed in that space. (i.e. a science version may require it) 5. It is pivotal in atmospheric flight in the Star Trek universe. Gosh, even kids and a Klingon know that... I was going to be sarcastic and then I really got into the thinking process. Fun.
I’m willing to go with the larger portion is heat sink while the smaller portion is a Jeffries tube or a turbo lift. Thus separating the really hot thing from where ppl have to traverse to do their job
Whenever I see a traditional saucer and secondary hull with nacelles on pylons design, I just want to add a brace between the two nacelles or extend the nacelles at the front so they connect to the primary saucer section (a bit like the Steamrunner class). If only the next film after Nemesis had gone ahead, apparently the same designers who did the new anti Borg First Contact ships were going to do a bunch of new Starfleet ships inspired by the Defiant - with a internal bridge and nacelles blended into the hull as the paradigm to show Starfleet is now tough and militant.
I started thinking about what they might be when I saw them too. I ended up figuring it could be explained as a segregated channel for things you didn't want interacting with warp plasma in the event of a containment failure. Like, it could either just be a turbolift or for sending material collected from the Bussard collectors to where it's processed in the ship. (I imagine keeping deuterium and plasma from interacting with one another inside your oxygen-rich ship would be a high priority concern for engineers.)
The prequel book said that the ship had a special refit for being in a nebula for a year and every part of the refit was for a smoother ride and better aerodynamics.
The world of star trek exists in such a strange space between Form vs Function. So much of the design is because they're so advanced, technology allows function to follow form. But then we have the technical specs and all kinds of things, and all kinds of things. There's definitely a push and pull between the two extremes for a lot of ships.
I used the Enterprise refit in a story once, it was, in the story, used because it fit the technology in the story and was an entirely human design (and the most beautiful starship design out there imo). The pylons in the story had ionic hydrogen reservoirs to trap heat converting the hydrogen to plasma and when the ship needed to release heat it would open vents on the back of the pylons to release the plasma into space. They never cover how they get rid of waste heat in the show but cutouts like that could be used to protect vents to release plasma. Such vents could be considered a weak spot that you'd want some extra protection on, the cutouts would help shield them and the hull of the pylons behind would easily endure the heat though it would absorb some making them a bit less efficient, trade off. In my story the nacelles were actually the powerplants and they generated a great deal of heat so separating them from the hull helped with heat management. Oh, and the bridge was in the center of the saucer, the top was an observation lounge. lol
The Enterprise from ST-TMP already had a waste heat management system with it's Flux Chillers on the inboard and outboard of each nacelle. Inboard they glowed blue. Also I think showing starships under construction with girders and beams is a nod to showing something familiar to the audience -- it's how we're used to seeing buildings under construction. Starships would almost certainly use a unibody/monocoque frame concept to reduce weight and add strength. Also, Structural Integrity Field. Since they have already figured out warp drive and transporters I would hope they had also figured out a way to convert that waste heat into another form of radiation that could be dispersed into the icy void much more readily than infrared heat.
I completely agree. Also, as an alternative I'd like to suggest a "skeleton" made of arcs and circles (a bit like a 3D-chainmail construct, with bigger spaces in between). Would give especially the Enterprise-D rigidity and flexibility.
if i remember right, Radiometric converter tech wasn't made until the 24th century. So the USS Enterprise 1701 would still have a problem with handling antimatter waste, radiation and cooling unlike those in the 24th century that recycled the waste back into other subsystems. So your explanation about regulating plasma cooling is awesome. i'd loved to explore more history about how starships handling waste and cooling. i still remember in TNG "Starship Mine" that a Baryon sweep was needed every 5 years or so, i wonder how Voyager got away with needing one after 7.
Make fun of DIS all you want by calling it Star Trek Gonorrhea, it doesn't change the fact that all the other series did the exact same thing you accuse DIS of doing.
@@paulmckenzie7126 This may come as a shock, but I don't lol. For the record, my insults are aimed at the show, not the people who like it. I don't like horror movies either, but I don't hate the people who do.
So far radiating heat is the only thing I have heard of that makes any sense. I'm glad you made a video on this as I think the only place I have heard this talked about was trekyards.
There is another angle to the heat concept: if the plasma conduits are in the area with the vents, and the pylons are also high load structural elements, then it may be helpful to isolate some of the support structure from the heat source. Heat tends to make metals more pliable, and keeping some of the metal at cooler temperatures can contribute to maintaining a desired standard of rigity.
Another possible explanation: when the constitution class first rolled out of the shipyard it just had the forward part of the pylon. After a year of shakedown the designers determined that the pylons were not quite strong enough and needed to be reinforced. The immediate solution was to add another set of pylons in parallel with the originals, leaving the small gap between them. Presumably this was intended to be a temporary addition to the constitution class while they go back to the drawing board and design a stronger and thinner pylon. By the time Kirk is in command the enterprise has undergone a small refit to replace the old reinforced pylons with the new design as seen in TOS.
When I first saw the cutouts they reminded me of the air-gaps in power-bricks, but instead of preventing the unregulated side shorting over to the regulated side, these cutouts prevent the active plasma from leaking their charge into the spent plasma.
Interesting topic! Smart analysis too. Two ideas I had (both could apply): Cutouts reduce scope for eddy currents induced in pylon metallic structure that might have undesirable magnetic or heating effects. Cutouts allow for inspection and maintenance access to - and easier swap-out of - certain components and structures.
I am interested by this idea of the ship trying to shed heat. I wonder if, taking this into consideration, cloaked vessels have to capture heat while cloaked instead of shedding it. Doing so would hopefully hide their heat signatures. This might explain the massive engine section of most Klingon/ Romulan birds of prey, and why they have the command section so separated and vulnerable. Especially when you look at a D'Deridex. This might explain their ability to not only travel at extreme speeds while cloaked, but look cool doing it. Poor Klingon engineers must be boiling when they are cloaked.
3:48 Sci-Fi is pretty dramatized, but in a matter of speaking you do freeze in space really quickly. The vacuum of space doesn't steal your heat, but it steals almost everything else from your body due to the lack of pressure. Most fluids would boil off of and to a degree out of your body, the gases escaping very quickly taking a lot of heat with them in the process that is now leaving your body, but some chemical bonds in fluids would remain strong enough to not accelerate away from your body, almost in a matter of speaking "freezing solid." So, there is some truth to the idea. Space isn't cold so much as it is just totally empty, and the matter making you up would tend to want to fill up that empty space as much as possible. In that process, taking heat away from you as well and it would be pretty fast. Maybe not seconds, but still pretty fast.
I came to here to say the same thing - a person wouldn't freeze solid immediately, but would accumulate a layer of ice very quickly as the liquid on and in the outermost membranes boiled in the vacuum.
Those are the attachment points for the polarity-inverted phased tachyon pulse emitter array manifolds. They're placed in the warp pylons so that it's easier to divert all power into them.
For what its worth, a canonical explanation for the cut out is the seperation of the plasma supplies between the Coils from the larger strut and a low volume delivery strut for the off axis field restoration devices at the rear of the Nacelle.
If I recall the blueprints of the refit correctly, the vents, which were on the forward and trailing edge of the pylons, were called "Emergency Flux Vents."
The additional surface area would work better in an atmosphere. But for radiative heat transfer the heat a surface emits is reabsorbed by the opposite surface. Corrugating would be more effective as the influence of cosine of the surface normal is reduced. Basically the zones in front and behind the pylon would get better heat illumination. IIR the side panels of the TIEs are structured that way! The main problem: whatever the cutouts do, internal bulkheads would most likely do the same thing, and potentially better. We use lead as radiation shield because you want as much mass between you and the source. Polished gold mirrors make better heat barriers then the gap. Maybe you could mount sensors in there, without getting them eroded by micrometeorites while reducing the shadowed sector in front? It's a long shot though...
The separation could be as a heat stop, the slot is used to prevent heat transfer through conduction. The hole could change the resonant frequency of the nacelle and prevent the nacelle from flying apart.
Since they increased its size from 289 meters to 442 meters , when the scaled it up( show) they probably saw that the nacelles needed extra support so they added the secondary support struts ( or it just didn’t look right with a huge flat single strut .
The problem with the idea of the cut outs being for radiating heat is that they don't increase the amount of surface area that is *facing out into space*. That extra surface area is pointing at each other, most of the infrared light being emitted by those surfaces isn't shooting off into space, its just hitting the other side of the cutout and being reabsorbed.
A cutout in the pylon would be an excellent place to store a droplet radiator system. After the plasma is used in the warp nacelles, the still hot gas/liquid is vented out one side of the pylon in tiny droplets. The insane surface area of this material sheds heat rapidly and is then collected on the other side of the pylon as the ship moves forward naturally.. While such a small gap limits the amount of cooling that can occur it would also limit the material loss.
The smaller beam might transport coolant to the blue glowing radiators on the inbound of the nacelles. The larger beam transports warp plasma, interstellar gas, hot coolant, and have transport tubes. The vacuum of space then helps insulate the coolant from the other one. Or maybe the warp plasma travels through the smaller one and the larger one is everything else. The point is that the smaller conduit is thermally isolated from the rest of the pylon by the conduit. This likely helps keep whatever is in there at a stable temperature.
No simplest explanation? If they send plasma through these, the cutout might be insulation protecting rest of the stuff that also needs to come through pylons against heat. Things that might be negatively affected by temperature might go through the narrow part, missing the vents (suggesting whatever was in it, wasn't hot).
It doesn't have to have a function in-universe either, Starfleet Ship Architects may have just had a thing for cut-outs in that era - most of the other designs bear that out. In about five years time, a new generation takes over that likes solid primary colors, solid struts, and byoootiful candy-button-encrusted consoles.
Radiating heat doesn't need a medium, that's why we get the heat of the sun through the vacuum of space. Convection doesn't happen though, that's where you do need some sort of fluid, either liquid or gas. So adding more surfaces to radiate heat from would help to lose heat
I read a star trek novel years ago. A junior officer needed to stop terrorists stealing the Enterprise. She wrapped a tractor beam in the nacelle strut and another on a nearby smallish moon and pulled! Kirk said to her ( later) "You bent my ship?" Lol the last line in the book was Scotty standing in her door "Lass, I'd like a word with ye." Oh that poor girl.
Holy shit. You came up with a plausible explanation. The cutouts won't bother me anymore. I can now happily rewatch SNW season 1 without feeling deeply uncomfortable during every exterior shot.
I would like to think that the rear, thinner portion of the pylons is actually where all the structural support for them and the nacelles is located, with possibly jefferies tubes running through it as well for maintenance of the nacelles. While the other, thicker portion would indeed perform some heatsink function, both for the Warp Drive's plasma conduits and maybe for the ship generally - I would imagine all the weapons on the Enterprise would also generate quite a lot of heat as well. Having a long, thin and flat structure, filled with heat tubes (whether plasma conduits or vapour chambers), running parallel to the main vector of the ship's acceleration is a cheap and efficient way of passively dissipating heat into the vacuum of space using only the vessel's movement.
This is why I love the Sci-fi genre. Show Designers: "SPACESHIP!!!". Show fans: "Here's some reasons that might work". Me: "Well I just learned a couple cool physics concepts in 5 minutes".
Henry, you need to be employed by CBS and school all the production staff. I love your informative, well-considered video essays - your super intelligent and have a great speaking voice too.
This probably won't have the same function on something the scale of a starship, but such a cutout on a smaller solid item would prevent a tear or crack from spreading. Real life examples would be car bumpers and fiberglass. If there are cracks in either and they're being repaired, prior to any material being added the ends of any cracks are drilled out to prevent the crack from spreading, as repairing something without doing so will eventually result in the crack simply spreading beyond the repair. I believe cracked metal is sometimes repaired with drilling the cracks out as well. It is for a similar reason why a windshield on a car with a small crack will soon need a full replacement in most cases, as the crack will eventually spread along the windshield. So my theory is that if the pylons were to be physically damaged such cutouts could help prevent total structural failure and having a nacelle fall free of the ship.
Another genius video. I wish I was this smart. I bet the writing staff for STD wish they were this smart. Keep up the good work. Someday they may tap you to save the franchise. 🙏🏻
thermal dissipation was my first thought. I'm fairly sure there are access ways into the pylons for repairs. I think one of the Command Level no-Win scenero's require you to send an officer into one of these to die in order to save the ship. it's possible one side (probably the thiner side) is for coolant input and personnel access and the thicker side is for the plasma input and output. there has never been any onscreen mention of thermal sinks so I think your right about that. it's logical that they didn't put them in on the original production line until they got the performance data back to see if the existing pylon structure would hold as it was. updating the design as understanding and advancement's came in. (coinciding with RW designers own understanding of engineering as they progressed themselves. )
because it sends the sense of hugeness, make the ship looks less like a thing that has been CNC out of a piece of material but a thing thats been put together buy many many parts to a point the suppose in-story-designer wasn't in pursuit for interior space anymore. eg. defiant will looks smaller however we look at it.
The cutout could be separating the plasma + cooling system from the access ways to the warp coils. This way the temperature in those power transfer systems doesn't have to be kept at temperatures suitable for humans.
A possible reason separate from what you said is that during manufacturing of Discovery’s version of the Enterprise, certain areas of the pylons needed to be readily accessible for construction and the speed of that construction. If pipes run through those pylons, then a break in the pipes could mean days of reconstruction compared to hours. If you ever built a water cooled PC then you know just how easy it could be to leak water all over your newly built machine when you start putting pressure through and how you could quickly ruin components if you don’t have immediate access to the loop. So in this case, imagine a plasma leak ruins a good chunk of components in a star ships pylon, rather than taking all the piping along with every single component in the way of the leak, just have quick access to the pylons center for repairs and construction. The down side is that the ship has less integrity like you said, but I would imagine that the ribs are now oriented vertically to try and make up for this loss. Perhaps the material just got stronger so they could afford that loss of integrity.
Well, original constitution model had 3 heat sinks just bellow Bussard collectors. It's possible that the cutout served as emergency warp plasma ejector
Lightening holes make sense in space too, since the more massive something is, the harder it is to accelerate under kinetic power (which is how Impulse Engines work, as opposed to Warp engines). Therefore, keeping your spaceship lightweight makes it easier to maneuver at sublight speeds when you're under impulse.
I would figure it would be because at some point the nacelles were upgraded and the additional pylon was needed for structural support and additional cabling and piping.
Great video, very interesting. I agree with the lightening holes theory and I agree with it being used to strengthen the nacelle pylons, but I disagree with the radiative cooling to some extent. Let me explain: the majority of the radiated heat goes in the direction the surface is facing. This means that the cut out radiator would be radiating heat into the other side of the cutout. And because materials absorb and emit radiation equally, the energy would be reabsorbed into the nacelle rather than radiated into space. Effectively, cutouts increase the total surface area of the pylon, but decrease the usable radiative cooling surface area. However, the cutout could be used for cooling if you channelled a hot coolant through it, confined by magnetic fields but radiating heat into space. Use a hot plasma, and you could get rid of a lot of waste heat quickly, and it would look cool.
Nope, it's stronger due to Arthur c Clarke's theory of perforation in toilet paper....the more there are, the less likely it will year at the perforations. Clearly a nod to sci Fi greatness.
I'm also assuming cutouts are also used to reduce material costs in the long run. It's kinda like how swords have grooves running parallel with the blades.
I would suggest that they are to add separation between the plasma conduits and a manway to the nacelles. Adding the vacuum of space between people and heat, radiation and potential hazards is a way cheaper and easier method of protection than say heavy armor or building specialized energy shields for the task.
It could also add separation between the coolant and the warp plasma. If the warp plasma heated the coolant, both would be less effective.
One section of the pylon channels plasma, and another channels coolant.
Exactly what I was thinking as well. And they could run control systems up one side and plasma through the other - physical separation means that, if the conduit blows out/leaks/fails (somewhat) catastrophically, you might still be able to do a manual shutdown or otherwise triage the situation.
EDIT: Plus, a vacuum gap is less likely to fail than energy shielding, and would presumably add less mass than radiation shielding plates or the like.
I like this idea
I was going to suggest this exact thing. Of course there is probably a jefferies tube running along side the conduit for maintenance, it is likely highly irradiated, but by have a separate tube as well it allows access to the nacelles without the need of a radiation suit along with a conduit for such things as the a fore mentioned coolant, wiring, GNDN pipes, and other support systems that probably wouldn't function as well when competing with the plasma conduits for heat expulsion.

100%. Not as badly as once structural support fields are introduced, which seem reliable enough that eventually the universe class throws structural sanity out the airlock entirely, but aesthetics seem to have always been a big consideration for starfleet designers. Which is a-okay, it obviously works well enough for them.

@Judge Dredd I know that. I was poking fun at Chris' comment.
The issue with your surface area statement is that most of the surface area inside the cutout is radiating /towards/ the face of another ship component, allegedly also a radiating/cooling surface. This means that that surface area isn't actually eliminating heat, because that heat is going back into your ship.
It could just be a separation of the in-flowing warp plasma and the plasma flowing back to the warp core. Ship designers saw the two magnetic "pipes," and thought "you know what, we could just cut out that section of the hull right there, and it wouldn't do anything. Why not?"
Exactly, good thing someone said this.
On the topic of heat radiation, I have always assumed that the warp grilles are actually heat radiators operating at very high (10000 Kelvin +, judging by their bluish glow) temperatures, to maximize radiance as per the Stephan-Boltzman Law:
𝑷 = 𝐴𝜀𝜎𝑇⁴
Where *A* is area, ε is emissivity of the radiator material, σ is the Stephan-Boltzman constant, and 𝑇 is the radiator temperature. As you can see, the temperature is to the power of four, meaning that doubling the radiator's operational temperature increases the amount of power it can radiate away sixteen-fold.
There are a few caveats to this idea however that I won't go into too much detail here unless anyone wants to know, but I find it a fun way to rationalise an iconic element of Trek ship design and solve the heat dissipation issue of these supposedly radiator-less ships.
The little fins on the TOS model were supposed to be radiators.... I think they underestimated the scale a tad.
Other possible invisible to us solutions could be high intensity lasers on a non visible part of the spectrum.
Ejecting heated particles from the hull to effectively create as large a radiator as you might need, this can be a total loss system as used on some real space craft or using the known tech of trek the particles can be reclaimed by some version of the various fields used by the ship already.
Dump your waste heat in subspace or something, invariably pissing off some native alien species for a single episode. Built in environmental message right there.
Sorry to bust your bubble, but that blue glow within the warp nacelles is the electromagnetic plasma interacting with the warp coils, thus generating the warp field. EM plasma-in and of itself-is invisible in a vacuum: no atmospheric gases for it to fluoresce.

Great video as usual! The cutouts alone would not increase the rigidity unless the edges are extended past the original surface. The airplane cutouts are a perfect example but notice how the sheet metal is bent out effectively multiplying it's thickness which increases rigidity.

God damn. This is the kind of content I live for.
The additional surface area is nullified by the opposing surfaces radiating all their heat onto each other.
That was my thought too. Then I thought, what if there were smaller angled structures in there to radiate the heat away at a 45° angle? They should do that with the whole surface of the pylon. With triangular prisms, you could increase the total surface area by a factor of 1.4...
And since it doesn't matter how small the triangular structures are that's probably what they'd be doing. And with this, the cutout makes sense again for cooling.
And why you even think that enclosed area inside pylon is equal to cutout and radiating energy out even if some of it just act on another side of cutout? Nullified is wrong word there and clearly you are wrong.
yup my thoughts exactly, the design doesn't make sense period. If heat radiation were the goal why isnt the entire surface full of radiators which are as close to blackbody radiators as possible ? a folded design, maybe even incorporating mirrors and lenses might be a realistic move ...
Very clever!
See, this is why I can't get accept the idea of a 'visual reboot, but it's still the same ship.' Like... the pylons have a hole, or they don't have a hole. Having a hole isn't just another 'look' for not having a hole. They're two very different things. So, I really can't accept them as being the same ship; it's a ship with holes in its pylons, or it isn't; it's not both. :-)
But... if the holes are there, this is a very plausible explanation for why. Bravo.

For your second point, I was under the impression futuristic shaped EM fields are use to prevent drive plasma from touching the walls of the conduit(s) and melting them. So the idea of keeping the conduits cool doesn't make a lot of sense because the plasma is not in direct contact with the conduit itself to transfer that heat.
Fields can contain the plasma itself, but it will still radiate heat. Also, if power goes down you need a mechanical fallback.
Also an electromagnetic system has much less resistance when cold. If they use a highly efficient superconducting magnet system, they would have to be keeping it very cold.
Exactly. The plasma doesnt need cooled anyway.

The cut could also change the vibration modes of the nacelles. Goes with the stresses you mentioned.

1. Allows the pylons and Na-cells to be flexible in turbulence.
2. The area has these Star Trek "thingy units" that produce Star Trek "thingies" in the space. Space smoke, space lighting, radar disruption features, sensor features.
3. Area collects required gas materials in Nebulous flight or high orbit gas planet flight to later be processed for long space duration flight - like Nobel gases required for life.
(like in Lost in Space season 2 when they collect the gases to clean the water system)
4. That particular version of pylon and na-cells do not have a flight or engineer system that would be in that usually housed in that space. (i.e. a science version may require it)
5. It is pivotal in atmospheric flight in the Star Trek universe. Gosh, even kids and a Klingon know that...

Are you going to make fleshed out models of the sidelined ships in Episode 9?
The potato peeler pylons are used to peel space potatoes clearly.
Whenever I see a traditional saucer and secondary hull with nacelles on pylons design, I just want to add a brace between the two nacelles or extend the nacelles at the front so they connect to the primary saucer section (a bit like the Steamrunner class).
If only the next film after Nemesis had gone ahead, apparently the same designers who did the new anti Borg First Contact ships were going to do a bunch of new Starfleet ships inspired by the Defiant - with a internal bridge and nacelles blended into the hull as the paradigm to show Starfleet is now tough and militant.
The star cruiser has pretty nice nacelles and pylons they are tucked in with the aft section of the ship instead of being extended super far out

I started thinking about what they might be when I saw them too. I ended up figuring it could be explained as a segregated channel for things you didn't want interacting with warp plasma in the event of a containment failure.

(I imagine keeping deuterium and plasma from interacting with one another inside your oxygen-rich ship would be a high priority concern for engineers.)

The world of star trek exists in such a strange space between Form vs Function. So much of the design is because they're so advanced, technology allows function to follow form. But then we have the technical specs and all kinds of things, and all kinds of things. There's definitely a push and pull between the two extremes for a lot of ships.
I used the Enterprise refit in a story once, it was, in the story, used because it fit the technology in the story and was an entirely human design (and the most beautiful starship design out there imo). The pylons in the story had ionic hydrogen reservoirs to trap heat converting the hydrogen to plasma and when the ship needed to release heat it would open vents on the back of the pylons to release the plasma into space. They never cover how they get rid of waste heat in the show but cutouts like that could be used to protect vents to release plasma. Such vents could be considered a weak spot that you'd want some extra protection on, the cutouts would help shield them and the hull of the pylons behind would easily endure the heat though it would absorb some making them a bit less efficient, trade off. In my story the nacelles were actually the powerplants and they generated a great deal of heat so separating them from the hull helped with heat management. Oh, and the bridge was in the center of the saucer, the top was an observation lounge. lol
My favorite channel on RUclips. Love these videos! And the Star Wars ships!
The Enterprise from ST-TMP already had a waste heat management system with it's Flux Chillers on the inboard and outboard of each nacelle. Inboard they glowed blue.
Also I think showing starships under construction with girders and beams is a nod to showing something familiar to the audience -- it's how we're used to seeing buildings under construction. Starships would almost certainly use a unibody/monocoque frame concept to reduce weight and add strength. Also, Structural Integrity Field.
Since they have already figured out warp drive and transporters I would hope they had also figured out a way to convert that waste heat into another form of radiation that could be dispersed into the icy void much more readily than infrared heat.
I completely agree.
Also, as an alternative I'd like to suggest a "skeleton" made of arcs and circles (a bit like a 3D-chainmail construct, with bigger spaces in between). Would give especially the Enterprise-D rigidity and flexibility.
Here before Star Trek steals this as the canon explanation
Do they actually do that?
if i remember right, Radiometric converter tech wasn't made until the 24th century. So the USS Enterprise 1701 would still have a problem with handling antimatter waste, radiation and cooling unlike those in the 24th century that recycled the waste back into other subsystems. So your explanation about regulating plasma cooling is awesome. i'd loved to explore more history about how starships handling waste and cooling. i still remember in TNG "Starship Mine" that a Baryon sweep was needed every 5 years or so, i wonder how Voyager got away with needing one after 7.
Can you please look at the SDF-1 Macross from SDF Macross.

So far radiating heat is the only thing I have heard of that makes any sense. I'm glad you made a video on this as I think the only place I have heard this talked about was trekyards.
There is another angle to the heat concept: if the plasma conduits are in the area with the vents, and the pylons are also high load structural elements, then it may be helpful to isolate some of the support structure from the heat source.
Heat tends to make metals more pliable, and keeping some of the metal at cooler temperatures can contribute to maintaining a desired standard of rigity.
Another possible explanation: when the constitution class first rolled out of the shipyard it just had the forward part of the pylon. After a year of shakedown the designers determined that the pylons were not quite strong enough and needed to be reinforced. The immediate solution was to add another set of pylons in parallel with the originals, leaving the small gap between them.
Presumably this was intended to be a temporary addition to the constitution class while they go back to the drawing board and design a stronger and thinner pylon. By the time Kirk is in command the enterprise has undergone a small refit to replace the old reinforced pylons with the new design as seen in TOS.
When I first saw the cutouts they reminded me of the air-gaps in power-bricks,
but instead of preventing the unregulated side shorting over to the regulated side,
these cutouts prevent the active plasma from leaking their charge into the spent plasma.
Interesting topic! Smart analysis too.
Two ideas I had (both could apply):
Cutouts reduce scope for eddy currents induced in pylon metallic structure that might have undesirable magnetic or heating effects.
Cutouts allow for inspection and maintenance access to - and easier swap-out of - certain components and structures.
I am interested by this idea of the ship trying to shed heat. I wonder if, taking this into consideration, cloaked vessels have to capture heat while cloaked instead of shedding it. Doing so would hopefully hide their heat signatures.
This might explain the massive engine section of most Klingon/ Romulan birds of prey, and why they have the command section so separated and vulnerable.
Especially when you look at a D'Deridex. This might explain their ability to not only travel at extreme speeds while cloaked, but look cool doing it. Poor Klingon engineers must be boiling when they are cloaked.
Well considering how hot Klingons like it, it was probably considered a design feature.
Mentions radiators on the International Space Station, while showing a picture of the MIR space station.
Great video, EC!
3:48 Sci-Fi is pretty dramatized, but in a matter of speaking you do freeze in space really quickly. The vacuum of space doesn't steal your heat, but it steals almost everything else from your body due to the lack of pressure. Most fluids would boil off of and to a degree out of your body, the gases escaping very quickly taking a lot of heat with them in the process that is now leaving your body, but some chemical bonds in fluids would remain strong enough to not accelerate away from your body, almost in a matter of speaking "freezing solid."
So, there is some truth to the idea. Space isn't cold so much as it is just totally empty, and the matter making you up would tend to want to fill up that empty space as much as possible. In that process, taking heat away from you as well and it would be pretty fast. Maybe not seconds, but still pretty fast.
I came to here to say the same thing - a person wouldn't freeze solid immediately, but would accumulate a layer of ice very quickly as the liquid on and in the outermost membranes boiled in the vacuum.
Those are the attachment points for the polarity-inverted phased tachyon pulse emitter array manifolds. They're placed in the warp pylons so that it's easier to divert all power into them.
For what its worth, a canonical explanation for the cut out is the seperation of the plasma supplies between the Coils from the larger strut and a low volume delivery strut for the off axis field restoration devices at the rear of the Nacelle.
If I recall the blueprints of the refit correctly, the vents, which were on the forward and trailing edge of the pylons, were called "Emergency Flux Vents."
It's used to vent off Delta Radiation
The additional surface area would work better in an atmosphere. But for radiative heat transfer the heat a surface emits is reabsorbed by the opposite surface. Corrugating would be more effective as the influence of cosine of the surface normal is reduced. Basically the zones in front and behind the pylon would get better heat illumination. IIR the side panels of the TIEs are structured that way!
The main problem: whatever the cutouts do, internal bulkheads would most likely do the same thing, and potentially better. We use lead as radiation shield because you want as much mass between you and the source. Polished gold mirrors make better heat barriers then the gap. Maybe you could mount sensors in there, without getting them eroded by micrometeorites while reducing the shadowed sector in front? It's a long shot though...
I love that the premise of this episode is "Hey, can we just all pretend that Star Trek was Star Trek again?"
The separation could be as a heat stop, the slot is used to prevent heat transfer through conduction. The hole could change the resonant frequency of the nacelle and prevent the nacelle from flying apart.
Since they increased its size from 289 meters to 442 meters , when the scaled it up( show) they probably saw that the nacelles needed extra support so they added the secondary support struts ( or it just didn’t look right with a huge flat single strut .
Now could you do the same for the cut outs and indentations on the nacelles?
The problem with the idea of the cut outs being for radiating heat is that they don't increase the amount of surface area that is *facing out into space*. That extra surface area is pointing at each other, most of the infrared light being emitted by those surfaces isn't shooting off into space, its just hitting the other side of the cutout and being reabsorbed.
A cutout in the pylon would be an excellent place to store a droplet radiator system. After the plasma is used in the warp nacelles, the still hot gas/liquid is vented out one side of the pylon in tiny droplets. The insane surface area of this material sheds heat rapidly and is then collected on the other side of the pylon as the ship moves forward naturally.. While such a small gap limits the amount of cooling that can occur it would also limit the material loss.
The smaller beam might transport coolant to the blue glowing radiators on the inbound of the nacelles. The larger beam transports warp plasma, interstellar gas, hot coolant, and have transport tubes. The vacuum of space then helps insulate the coolant from the other one. Or maybe the warp plasma travels through the smaller one and the larger one is everything else. The point is that the smaller conduit is thermally isolated from the rest of the pylon by the conduit. This likely helps keep whatever is in there at a stable temperature.
I got no trouble with them EC. They look cool. And happy late new year bro.
No simplest explanation? If they send plasma through these, the cutout might be insulation protecting rest of the stuff that also needs to come through pylons against heat. Things that might be negatively affected by temperature might go through the narrow part, missing the vents (suggesting whatever was in it, wasn't hot).
It doesn't have to have a function in-universe either, Starfleet Ship Architects may have just had a thing for cut-outs in that era - most of the other designs bear that out. In about five years time, a new generation takes over that likes solid primary colors, solid struts, and byoootiful candy-button-encrusted consoles.
Radiating heat doesn't need a medium, that's why we get the heat of the sun through the vacuum of space. Convection doesn't happen though, that's where you do need some sort of fluid, either liquid or gas. So adding more surfaces to radiate heat from would help to lose heat
I read a star trek novel years ago. A junior officer needed to stop terrorists stealing the Enterprise. She wrapped a tractor beam in the nacelle strut and another on a nearby smallish moon and pulled! Kirk said to her ( later) "You bent my ship?" Lol the last line in the book was Scotty standing in her door "Lass, I'd like a word with ye." Oh that poor girl.
Holy shit. You came up with a plausible explanation. The cutouts won't bother me anymore. I can now happily rewatch SNW season 1 without feeling deeply uncomfortable during every exterior shot.
I would like to think that the rear, thinner portion of the pylons is actually where all the structural support for them and the nacelles is located, with possibly jefferies tubes running through it as well for maintenance of the nacelles. While the other, thicker portion would indeed perform some heatsink function, both for the Warp Drive's plasma conduits and maybe for the ship generally - I would imagine all the weapons on the Enterprise would also generate quite a lot of heat as well. Having a long, thin and flat structure, filled with heat tubes (whether plasma conduits or vapour chambers), running parallel to the main vector of the ship's acceleration is a cheap and efficient way of passively dissipating heat into the vacuum of space using only the vessel's movement.
Radio frequency energy like microwaves don't travel in solid conductors but tube like waveguides. The slot could be a form of energy waveguide.
This is why I love the Sci-fi genre. Show Designers: "SPACESHIP!!!". Show fans: "Here's some reasons that might work". Me: "Well I just learned a couple cool physics concepts in 5 minutes".
Henry, you need to be employed by CBS and school all the production staff. I love your informative, well-considered video essays - your super intelligent and have a great speaking voice too.
It separates the mechanical part (vents?) and the people part (elevators?). It also directs buckling away from the saucer section.
This probably won't have the same function on something the scale of a starship, but such a cutout on a smaller solid item would prevent a tear or crack from spreading.
Real life examples would be car bumpers and fiberglass. If there are cracks in either and they're being repaired, prior to any material being added the ends of any cracks are drilled out to prevent the crack from spreading, as repairing something without doing so will eventually result in the crack simply spreading beyond the repair. I believe cracked metal is sometimes repaired with drilling the cracks out as well. It is for a similar reason why a windshield on a car with a small crack will soon need a full replacement in most cases, as the crack will eventually spread along the windshield.
So my theory is that if the pylons were to be physically damaged such cutouts could help prevent total structural failure and having a nacelle fall free of the ship.
Another genius video. I wish I was this smart. I bet the writing staff for STD wish they were this smart. Keep up the good work. Someday they may tap you to save the franchise. 🙏🏻
thermal dissipation was my first thought. I'm fairly sure there are access ways into the pylons for repairs. I think one of the Command Level no-Win scenero's require you to send an officer into one of these to die in order to save the ship. it's possible one side (probably the thiner side) is for coolant input and personnel access and the thicker side is for the plasma input and output. there has never been any onscreen mention of thermal sinks so I think your right about that. it's logical that they didn't put them in on the original production line until they got the performance data back to see if the existing pylon structure would hold as it was. updating the design as understanding and advancement's came in. (coinciding with RW designers own understanding of engineering as they progressed themselves. )
Hey echenry! I have always enjoyed your videos and keep up the good work! How is the fan film coming along?
Well thought out!
because it sends the sense of hugeness, make the ship looks less like a thing that has been CNC out of a piece of material but a thing thats been put together buy many many parts to a point the suppose in-story-designer wasn't in pursuit for interior space anymore.
eg. defiant will looks smaller however we look at it.
The cutout could be separating the plasma + cooling system from the access ways to the warp coils. This way the temperature in those power transfer systems doesn't have to be kept at temperatures suitable for humans.
A possible reason separate from what you said is that during manufacturing of Discovery’s version of the Enterprise, certain areas of the pylons needed to be readily accessible for construction and the speed of that construction. If pipes run through those pylons, then a break in the pipes could mean days of reconstruction compared to hours. If you ever built a water cooled PC then you know just how easy it could be to leak water all over your newly built machine when you start putting pressure through and how you could quickly ruin components if you don’t have immediate access to the loop. So in this case, imagine a plasma leak ruins a good chunk of components in a star ships pylon, rather than taking all the piping along with every single component in the way of the leak, just have quick access to the pylons center for repairs and construction. The down side is that the ship has less integrity like you said, but I would imagine that the ribs are now oriented vertically to try and make up for this loss. Perhaps the material just got stronger so they could afford that loss of integrity.
Well, original constitution model had 3 heat sinks just bellow Bussard collectors.
It's possible that the cutout served as emergency warp plasma ejector
Lightening holes make sense in space too, since the more massive something is, the harder it is to accelerate under kinetic power (which is how Impulse Engines work, as opposed to Warp engines). Therefore, keeping your spaceship lightweight makes it easier to maneuver at sublight speeds when you're under impulse.
Bloody marvelous ❤.
It’s Discovery, nothing in that show makes sense
I live your videos so much I watch your star trek videos even though I've never seen star trek. There just so engaging and interesting
I would figure it would be because at some point the nacelles were upgraded and the additional pylon was needed for structural support and additional cabling and piping.
Great video, very interesting.
I agree with the lightening holes theory and I agree with it being used to strengthen the nacelle pylons, but I disagree with the radiative cooling to some extent.
Let me explain: the majority of the radiated heat goes in the direction the surface is facing. This means that the cut out radiator would be radiating heat into the other side of the cutout. And because materials absorb and emit radiation equally, the energy would be reabsorbed into the nacelle rather than radiated into space. Effectively, cutouts increase the total surface area of the pylon, but decrease the usable radiative cooling surface area.
However, the cutout could be used for cooling if you channelled a hot coolant through it, confined by magnetic fields but radiating heat into space. Use a hot plasma, and you could get rid of a lot of waste heat quickly, and it would look cool.
Nope, it's stronger due to Arthur c Clarke's theory of perforation in toilet paper....the more there are, the less likely it will year at the perforations. Clearly a nod to sci Fi greatness.
I'm also assuming cutouts are also used to reduce material costs in the long run. It's kinda like how swords have grooves running parallel with the blades.
